devices for coupling the rubber tip or end of Be it known that I, CHARLES SAUTTER, a kcitizen of the United States, residing at West llobokcrn'in the county of Hudson and StateA lol' Newv Jersey, have invented certain new kand useful Improvements in Gas-Hose Coup-- lings, of which the followin is a specification, reference being had to t e accompanying drawings.

This invention relates to improvements in a gas tube or hose to the nipple of a gas stove, ygas burner or the like.

yThe object of the invention is to provide a simple device of this character which-will be p strong and durable, which may be applied to anygas hose or tube connection and which will effectively stop the 'leakage of gas, es-

"pecially when the rubber tip or end of the hose has become stretched and worn.

lith the above and other objects in view,y the invention consistsA of the novel features ofconstruction and the combination and arl ran ement of paits hereinafter fully'descri ed and claimed, and illustrated in the L `accompanying drawings, in which- Figure 1 is a side elevation of the improved ycoupling or clamping device showing the same in use; Fig. 2 is a longitudinal section; and Fig. 3 is a transverse section taken -on theplane indicated by the line 3-3 in Fig. 1

In the drawings 1 denotes a gas hose or tube and 2 the usual rubber tip applied to its f ends for the k purpose of connecting it to the 'tapered nip e 3 of the gas pipe 4 of a gas stove, drop ight, or the like or to the end of a gas pipe or connection of an descri tion.

5 denotes the improved coup ing or c amping device which is adapted to clam pl the'rubber tip or end 2 of the hose upon t e nipple 3 to prevent leakage of gas. The device consistskof two members', 7 sleeved together and having a screw threaded engagement.v

` rAs illustrated, both members are tubular to receive the rubber tip 2 and their exterior surfaces may be provlded with annular rows of radiating fingers or projections or otherwise shaped to permit them to be .readily grasped between the fingers and turned with respect to each other to tighten o1' loosen the coupling. The inner member 6 has the finers 8 at one of its ends while its other end 9' lsbeveled and externally screw threaded, as shown at 10. The outermember 7 has one of its ends internally screwr threaded, as at 11, to receive the screw threads 10 and the the escape of gas between said parts.

fingers or projections 12 are formed at its opposite end. At the last mentioned end of the member 7 is formed an enlarged portion .or annular channel 13 which forms a seat for a clam ing ring 14. The latter is preferably 1n the orm of a coil spring bent into circular form and sprung into the seat 13, said seat.,

being of less depth than the diameter of the spring whereby the beveled end 9 of the member 6 will engage the spring upon one side .andwhen the two members are screwed together will force said spring against the y outer wall 15 of the seat or channel 13, which wall is beveled outwardly, as clearly shown in Fig. 2 of the drawings. vOwing to the elasticity of the sprin 14 it will be seen that when the end 9 o the member 6 forces it against the beveled or inclined wall 15 of the lseat 13, the spring-will be c-ontractediand caused to tight y bind the rubber tip 2 upon the nipple 3, therebyeffectively preventing making the clamping ring 14 from a coil spring it will contract readily and adapt itself to vthe size and shape of the rubber tip 2 and the nipple 3, it will also sli readily over vthe tip 2 in being adjusted an it will be exceedingly strong and durable. It will be further noted that the peculiar construction of the device renders it exceedingly inex ensive to manufacture, eas to apply an yremove and durable and e ective orl the purpose intended.

Having thus described the invention what is claimed is: y

1. A device ofthe character described comprising two members sleeved together and aving a screw threaded engagement, and a coil spring bent into circular form and arranged in one of the members and adapted to be expanded and contracted by the movement of said members with respect to each l other.

2. A device of thecharacter described comrising two members sleeved together and having a screw 'threaded engagement, one of said members bein formed with an annular seat having a beve ed wall and a coil spring bent'into circular form and sprung into said seat and adapted to be engaged by the other member and to be forced against ,the beveled Wall of said seat when the members are screwed together, whereby said spring will be contracted to clamp a hose upon a nipple.

3. The combination with a hose and a nipple projecting linto the same, of a clamping device consisting of two tubular members sleeved together and having a threaded en gagement, one of the members bein formed with an annular seat having a beve ed wall,y

and a coil spring bent into circular form and sprun into said seat, said spring being arrange upon the hose at the point of its engagement with the nipple whereby when said members are screwed together the end of one threads andat its other end with an enlarged annular channel 'to provide a seat, the other member having external screw threads to engage the internal threads on the first mentioned one and having its inner end inwardly beveled, and a coil spring bent into circular form to provide a clamping band which surrounds the elastic hose and is ar- 'ranged in the channel or seat in one member and engaged by the beveled end ofthe other, whereby said clam ing spring is expanded and contracted by t e movement of the members with respect to each other.

In testimony whereof I hereunto ailix my signature in the presence of two witnesses.
